1. Details of the Drunk Driving No Suspicion of Crime Case
This is the account of a client who sought the assistance of this firm's drunk driving attorney specialist, asking him to bring about a finding of no suspicion of crime.
The client said that he had drunk one cup of makgeolli at a workplace gathering, and about 20 minutes later, while driving his own vehicle home, he was caught in a police crackdown.
The blood alcohol concentration measured during the crackdown was confirmed to be 0.036%, which slightly exceeded the statutory punishment threshold for drunk driving of 0.03% under the Road Traffic Act.
Considering his image at work, potential future disadvantages in personnel matters, and his family's livelihood, the client absolutely needed to avoid punishment and retain his license, and so at the early stage of the case he promptly requested the assistance of a drunk driving attorney specialist at Daeryun Law Firm.

Assistance Provided by the Attorney
From the early stage of the case, the drunk driving attorney specialist set out to build a strategic defense logic centered on scientific and legal grounds rather than a mere emotional appeal.
1. Review of whether the blood alcohol concentration was in its rising phase and the possibility of back-calculation
Because the measurement was taken about 40 minutes after the client had been drinking, the situation could fall within the commonly known rising phase of blood alcohol concentration (approximately 30 to 90 minutes after drinking), and so the attorney argued that the blood alcohol concentration at the time of driving may have been lower than the measured value.
This was used as a basis for persuading the investigative agency, in accordance with the following precedents and scientific grounds.
Supreme Court Decision 2002Do6762 "Even if a measurement taken afterward slightly exceeds the punishment threshold, the value at the time of driving cannot be conclusively determined."
Seoul Northern District Court Decision 2022Gojeong1244 "Alcohol concentration may vary depending on individual constitution, the amount of alcohol consumed, whether a meal was eaten, and other factors, and if it was in the rising phase, it may have been lower than the measured value."
2. Submission of evidence of the client's personal circumstances and efforts at improvement
The drunk driving attorney specialist submitted materials proving a concrete will to improve, as follows.
Submission of a statement of reasons regarding anticipated disadvantages related to occupation and livelihood
Submission of personnel evaluation materials regarding his social role and work attitude
Submission of a written apology establishing that he was a first-time offender, that there was no intent or circumstance of dangerous driving, and that there was no likelihood of harm or responsibility for any resulting consequences
The drunk driving attorney specialist submitted these materials and argued that no accident, property damage, or conduct endangering a third party had occurred at all, and, having also considered the possibility of restorative measures, that the need for criminal liability was low.
In addition, the defense counsel's written opinion was prepared and submitted with structured reasoning grounded in legal principles, precedents, medicine, and behavioral analysis, and an attorney accompanied the client at every stage of questioning to ensure consistency of statements and to prevent defense errors.
2. Result of the Drunk Driving No Suspicion of Crime Case
The investigative agency comprehensively considered the possibility of the rising phase of blood alcohol concentration presented by the drunk driving attorney specialist, the scientific and legal grounds, the personal circumstances and absence of any likelihood of reoffending, and the absence of any resulting harm, and issued a decision of no suspicion of crime (non-referral).
